Architecture

There are two deployment modes of CLM:

• Standalone - CLM is deployed on a single bare metal server or virtual machine (VM).

• Redundant - CLM is deployed on two bare metal servers or VMs. There is an active and a standby instance of the CLM in this deployment mode.

The following Figure shows the architecture of CLM.

Figure 1-1: CLM architecture

CLM comprises of an administration portal and a server. The CLM administration portal is a user interface (UI) that allows an operator to perform administrative functions such as uploading licenses and viewing notifications.

The CLM server has the business logic for license management. The network license pool is maintained here for each network function type, as defined by the network pool key. A network pool key is a file that defines the quantity or pool of ASLs for a specific network function.

Note: The operator must acquire the network pool key for the specific network function type and version from the Nokia Supply Chain.

License entitlement for a network function involves license pool capacity reservation. The CLM server communicates with the managed network functions as well as the license key repository that is used to store the license keys used by the network functions. The CLM allows an operator to configure, manage, and monitor the license key deployment.
